What is the explicit equation for f(0)=8; f(×)=f(×-1)*3
andriy [413]

Hello from MrBillDoesMath!

Answer:

f(x) = 8 * 3^x


Discussion:

x = 0:      f(x) = 8

x = 1:       f(1) = f(0) * 3 = 8*3

x = 2:      f(2) = f(2-1)*3 = f(1) * 3 = (8*3)*3 = 8 * 3^2

x=3 :       f(3) = f(3-1)*3 = f(2)*3 = (8 * 3^2) * 3 = 8 * 3^3

Based on this we guess that

f(x) = 8 * 3^x


Thank you,

MrB

After being hit, the puck travels along the ice at a constant speed. What might cause his motion to change?
Firdavs [7]

Answer:

<em>Hi! Todo here!! UwU</em>

Step-by-step explanation:

Even if the puck is on ice, I wouldn't automatically assume no friction. Otherwise hockey pucks could be tapped slightly and potentially go across entire arenas. I'd say include at least a small friction force opposing motion.

<em>Hope This Helps!!!</em>
